8:00 earn, top of the hour, i'm joining you live from new york, a lot of news this evening including this, insiders at nbc news say what is happening at their network is a slow motion car wreck and journalists are wondering if brian williams will again anchor.

he will not be behind the desk for several days. they say he voluntarily temperatured down temporarily feeling that the swirling credibility scandal makes him hooch of too much of a part of the news right now. a short time ago, a news anchor mentioned his decision to step down. a word tonight about our colleague brian williams who has been under scrutiny this past week. this afternoon he issued a statement that says in part it has become painfully apparent to me that i am presently too much part of the news due to my actions. i have decided to take myself off of my daily broadcast for the next several days, his full statement can be found on the website. >> okay, interesting development that the other nightly newscast, abc and cbs have not covered

this until tonight. >> all three acknowledged brian williams leave of absence tonight. it is a big cultural story. because you know i try not to get into it, but brian williams is the closest thing we have to walter cronkite. and for most people, nbc equals nbc news. to have him to step aside out of this public glare for a few days, if not longer, is real damaging, but he did make a decision, issued a statement, that he is stepping down to sort this out, and that he will be back. >> yes, he emphasized that in his statement, said he will return and regain the trust of his audience. every day you gain trust or regain trust or keep their trust. brian williams lost some people's trust in this story and he will have to work to gain it back overtime.

that is if nbc lets him. there has been not but real silence at nbc him. >> i wonder what you think of the statement that we got from the nbc president that is initially a staff memo saying of course we're investigating this, we will give you a update, what they did not do is run to the supporter backing of brian williams. >> there was no message of support. you can imagine lots of ways they could have expressed support. i just talked to a person that has been at nbc for years. like everybody is talking about this. they said to me the company is giving itself a way out if that's what they end up wanting to have. they are giving themselves a way out by having brian williams step aside for a bit and having lester holt fill in for the time being. it is now a ticking clock. now every day, folks will wonder -- >> is he back on -- >> in this very tight knit tv

news business. and every night that he is not back on we will probably look back. >> you mentioned facebook, and this might not have transpired without facebook? >> yes, social media has really changed everything. his comments on the nightly news about having his helicopter being hit by an rpg when that apparently didn't happen. they were broadcast on friday night, and soldiers started saying hey, buddy, we were on that chopper and you were not there with us. he had to address it. some people say the apology was not enough. without social media in this case this would not have happened. brian williams has been somewhat resistant to social media. he famously has a twitter account that a quarter million people follow but he has never

twe tweeted. so it is irony and sadness that it was social media that brought this to the forefront. so when he started to exaggerate his story, social media was nonexistent. >> so you will talk about it in your show at 11:00 a.m. eastern. >> yes, we'll see if chuck todd says anything. also this, i want to bring you news we have been following, bruce jenner involved in a car accident. he was not injured, but that is all we have at this point in time. they're saying one person is dead, five others are hospitalized with injuries after what turned out to be a four-car crash. absolutely tragic. the person killed was driving one of the cars and was pronounced dead at the scene. we don't know who died or the

names of the five injured and hospitalized right now. this happened on the pacific coast highway in malibu. joining me now is mark garagos. i understand you have new was about the investigation that has been launched? >> i talked with people from the sheriff's department, they ratcheted this up to a have hick lar homicide investigation. they also asked for and my sources tell me they have or are in the process of getting blood alcohol results from everyone involved in this. it is true there is a fatality and they will. >> just to be clear here, all of

the reporting that we have says that have hick lar manslaughter investigation, is that what you're hearing? manslaughter? >> that's exactly what i'm hearing. to ratchet this up to a murder investigation, you would have to have somebody that is responsible for the death in the vehicular accident to have a prior conviction, or to be driving incredibly recklessly or something like that. so far there is no kind indication that is the case. >> let's be very clear here, bruce jenner is the name across the screen and the photos because he is a celebrity. we don't know anyone else involved. however, everyone in these cars is being looked at right now in this investigation, is that correct? >> that is absolutely correct. everyone in it, and by all accounts so far, and what i'm being told, it is a multicar collision. so he is not the only one involved.

it is kind of like dominoes where there is a succession of cars involved. but i will tell you that i am also told, and not through the sheriff, that his family or his people have already reached out to an attorney, and it will become apparent shortly it is one of the usual suspects, and that he is cooperating by all accounts. and that this would be the normal course of action where it would be investigated as a vehicular manslaughter. and there is no kind indication at this point that it is a murder, and in california, you can have a murder investigation, or a murder charge when it is a vehicular accident. there is no indication at this point that this is what's going on. >> and we reported that bruce jenner willingly took a breathalizer test on scene, will there be any blood tests or

other tests done on the people involved in this crash? >> yes, i would be shocked if there wasn't, and i don't have any information other than my experience in this. even if there is a breath test taken, and even if we came back at a .00, i would be shocked if they didn't take him for a blood test. i would be shocked if his own lawyer didn't recommend that he immediately go to a hospital and get what is called a tox screen and they take the blood and run all drugs, you don't want any suggestion that it was chog or some other drug. that can be just as bad for you. >> again, everyone being looked at in this investigation, we appreciate it very much, mark geragos, thank you for the reporting. >> thank you. also, this stop story, the family of u.s. hostage kayla mueller says they're hopeful

they're beloved daughter is still alive. the message for isis, next.

two parents in arizona making an emotional plea to isis. they want isis militants to contact them immediately about their beloved daughter. the united states has major doubts about the claims that a

jordanian airstrike killed mueller. they have not received recent proof of life from her captors. the target struck friday by the royal jordanian air strike. we have seen no indication that hostages were being held at this location. we continue to review and evaluate all information. we travelled to her hometown to learn more about this young woman, what compelled her to help the people of syria. >> police closed off the street leading to the mueller family home. kayla mueller's mother and father grapple with how a child who could give so much is trapped in brutality. but it was the very atrocities of war that drew mueller. in syria she felt pulled to help the victimized. >> i'm in solidarity with the

syrian people. i reject the brutality and killing that the syrian authorities are committing against the syrian people. >> by the following year, she would make her first trip to the syrian and turkish border. even growing up, she longed to engage the in wrongs of the world. >> my daughter is one of those folks that looks for the good in everything. and in that vain, she goes on ahead and tries to look for her god center with the way she looks and acts for day today life. >> she was shone mwn marching through town, staging silent protests against genocide. as a student at northern arizona university, mueller was present at a student led movement to end

brian williams is off the

desk right now at nbc nightly news from his fallout of an on-air apology he made saying he did not tell the truth about a situation in iraq in 2013. lester holt will fill in for brian williams for at least the next few days. in california, bruce jenner was involved in an accident today. the olympian turned celebrity was not injured in the accident. it happened in malibu and the los angeles county sheriff's office says one person is dead and there are five or six other people injured and being treated at the hospital. this is a four-car crash. a vehicle manslaughter investigation has been opened. everyone involved in the crash is part of that investigation.

paul, what are you hearing about those injured? >> we're hearing that they're all children or minors and that number is a discrepancy right now. the fire department saying five or six were injured. what we know about this is it was a chain reaction and basically bruce jenner's black escalade was in the middle of it, and his car hit a white lexus that went into another lane, into oncoming traffic, and this black hummer or hum vee hit the lexus. the front end caved in and the woman driving that car was reportedly dead on arrival. jenner took a breath test on scene. all witnesses have been cooperating with the

investigation. this is right next to the pacific ocean. on a dangerous road. five moi nor-- minors injured i the crash. thank you for that, also the tragedy surrounding the discovery of finding bobb bobbi kristina brown a face down in a bathtub. >> nick gordon, the man she calls her husband, police investigators want to figure out what happened in the hours that lead up to police finding her face down in that tub. as far as her condition, the hospital has been very kwquiet about her condition, and she is still in a medically induced

coma. this is still treated as a medical incident, but right now all eyes and attention are on nick gordon. >> nick, thank you for that. switching gears now, imagine being in a serious relationship with your husband, a boyfriend, a girlfriend, and others you dated on the side. this is part of our special "sex and drugs in the silicon valley." what, in reporting this out, what did you find that really shocked you the most? >> my god, well, i went into a high tech swingers party so that was shocking, but i think it was just how far people are willing to go when it comes to silicon valley, they question everything. they're also questioning the most personal societal values. should we be in one relationship? are drugs that bad? let's try it out and test it out. >> everything from lsd to brain

enhancing totally legal vitamin type drugs. >> yeah, dave, this is what he calls his stack. he takes about 15 smart drugs a day, and this combination help him with brain fog, stay up longer, code better, and it is an idea of trying to maximize and optimize. and when applied to this it is weird but interesting. >> fascinating. thank you lori for bringing it to us. coming up next, a special "sex and drugs in the silicon valley. thank you for being with us, thank you for being with us, have a great evening. ife insurat just insuring our lives... we're helping protect his. [ female announcer ] everyone has a moment when tomorrow becomes real. transamerica. transform tomorrow.

sex can be hacked. experimentation is the foundation of silicon valley, and now it is going from your gadgets to your personal life, pushing boundaries even farther, challenging society's personal values. how we love, applying data to dating, and using drugs to enhance mental performance. it has sparked a cultural revolution. if the current wave is changing the way the world works, could

the next wave change how the world thinks. we look at the weird, the disruptive, and how the innovator's next target could be your life. ♪ ♪ better, faster, stronger >> harder, better, faster, stronger. it is not just a kanye west song, it is also an ethos in the tech world. >> gabba wave, it doesn't taste great, but it's worth it. >> you take all of these, put them in your hand, and just take them, is that safe to do? >> it is totally safe. i look back to my college days when we had beer bongs, it's the same concept. >> you're thinking this dude is crazy, i thought so too. he is the ceo of bullet broof,

an entrepreneur, and he is known for experimenting with drugs, the smart ones. >> i want to age less quickly, i want the most energy, and having a brain that works really, really well. when i was 300 pounds, i had problems with brain fog. >> that combo he is downing, that is what is referred to as a stack. smart drugs. they're aimed at enhancing your brain. from a stimulant like coffee to a drug. smart drugs, whatever you call them, users say they enhance your brain and your body's performance. they are a thing in the tech world in part because of the high levels of competition, and in part because of the long hours. it comes down to bio hacking. the idea that we can control our biology and program it to

maximize results. for days, maximizing results meant escaping. more than 800 miles north of san francisco and british columbia. >> the whole idea is this idea of hacking the status quo, not taking things at face value. is this your way of doing that? >> your body will respond to the environment it's in. when i look at the way my meat, my biology, my body responds to the body around me, i am more resilient, and i thrive when i have views like this. >> dave says smart drugs saved his life, but it's hard to know how safe they are. people can suffer from side effects, headaches, insomnia, and many have not been studied. >> i have used everything you can imagine. i -- the list goes on and on.

>> tim's body is essentially a living lab. he also practices bio hacking. there are no limits. >> here in silicon valley, you're your own athlete. smart drugs are away to help achieve that marathon. >> you're a 23-year-old start up co-founder. just got a seed round of funding, just like an olympic athlete who is willing to do almost anything, even if it shortens their life to get a gold medals, you will think about. it the difference between making a million dollars and a billion dollars is right here. >> let's look at 10 and 15 years, if you do have horrific side effects, will it have been worth it? >> i had side effects. i tried an extreme form of kotosis, i got extreme food allergies i didn't have before.

if i find out there was side effects, will it have been worth it? yes. the quality of my life every day is so much higher now than it was ten years ago that it is priceless. >> coming up, meet the man who went on an acid trip with steve jobs. grandpa bode, grandma said you used to really... control. i guess i did take some risks. anncr: bode, bode miller!!! trained a little bit differently. a little too honest sometimes. the media is useless. you were out of control. but not always.

part of the success in silicon valley is about your brain. the other part is creativity. the ability to think outside of the box. to have a breakthrough moment, turning your millions into billion billionaires. >> the billionaires i know use that li drugs on a regular basis. >> the creativity comes from drugs? >> the people i know who are trying to be very disruptive, and look at the problems in the world that exist, and ask completely new questions. they might look at something that has troubled us for hundreds of years and see something for completely

different. >> i was at a science fiction convention, and a grateful dead song came on the radio, and it was like that is why people listen to grateful dead on lsd. >> he has been using lsd for decades. he currently works as an engineer for cisco. >> how high would you say is the premium on creativity in silicon valley. >> everything we do is entirely creative. it requires creative solutions. and lsd kind of fits into that because you get a magical breakthrough. i would be at a grateful dead show, high on lsd, doing drugs, and then something about my work would just come to me. i had been working on a problem for over a month, all of this hard work, and i took lsd and i just realized, wait, the problem is not a software problem at

all, i come back to work, tell my manager he had an epiphany. >> there is scientific proof that lsd could do just that. one study funded in the '60s took a group of scientists and sent them out to solve 48 different problems. problems the scientists themselves had been unable to solve. each one was guided through a psychedelic trip. at the end of which 44 of the 48 problems were solved. >> that is daniel kottke, one of apple's first employees. before we knew steve jobs, he knew him as the guy he used to trip with in college. >> he said lsd was one of the best things he ever did, why is that? >> it expands your

consciousness. conversely, steve was never interested smoking pot, that did not expand conscientiousness. >> we don't know as much about the human brain or body as we think we do. we're absolutely medieval. i think we will look back at our behavior and it is going to look like blood letting in the dark ages. >> coming back, the hidden swinger scene. for just $100 bua month. it's america's best unlimited family plan. and it's only at t-mobile. i know... this third shift is rough... it's just a few more weeks

max! what are you doing up? it's late. i just wanted to have breakast wih you.

it is a story most of us heard as a child. you grow up, get married, get married, and live happily ever half. it is not always true. for some the definition of love, rips, is evolving. here it is a different story. >> my fiance and i practice partner nonmonogamy. we live together, and each other's needs come first, he is my primary, and then we see other people. >> how many relationships are you in? >> i'm in four right now. i have been seeing a woman for two years. i also see a man about once a

month, and then i have my distraction spot for whoever happens to be catching my attention at the time. >> miju is an engineer at a tech company. her relationship is polyamorous. miju decided to challenge the status quo. >> people in silicon valley are always looking for ways to change norms. in technology, people have higher appetites for risk. opening your relationship is risky in a similar way to starting a company is risky. >> polyamory is not new. it's roots date back to the 19th century in upstate new york where they conducted a experiment. it was called complex marriage.

a century rather, another it ter ration on nonmonogamy became popular, it was in the '60s. technology is connecting people looking to experiment while lifting the curtain on counter culture. one man started the use of the twitter hashtag, and he is also nonmonogamous. >> if you're trying to build a product, let's say, and it is failing 50% of the time, you might want to consider the design and think of ways to improve that. it's not to say that mo nothinos wrong, it's just not right for some people. >> 5% of americans are involved in consensual nonmonogamous

relationships. there is many types of love. we got the drive to pair up many years ago, and along with that came a lot of jealousy. >> dr. hellen fisher is a anthropologist and she studies sex and human relationships. >> do most succeed or do most fail? >> eventually they will probably all almost fail. the human brain is not good at sharing. >> another problem is the concept of open marriage. you may call it swinging, but today it is called the lifestyle. >> can you explain what happens at these events? >> if you have a bar or a nightclub you have the majority of it. there is just an extra twist.

at a bar you might take them home if you're single were here it is not unheard of to do that even if you're married. >> they have been together for ten years and having sex with over people for two of them. they're part of a community that explores their sexuality. in the 60s, there was parties where married couples attended. men would put their keys into a bowl and a woman would pick up the key and go home with him. for certain communities, the mobile device is the key. and tech is connecting modern day high-tech swingers. >> the mobile phone is a great tool. we have a thing called auto-date which allows you to choose the people you're interested in. if you choose it and they choose it, it is a notification.

>> a modern day key. >> now he is using his tech background for a new venture and this one is a bit more out there. >> you own bronze party, what is bronze party? >> it is a lifestyle event, a upscale lifestyle event. it starts at like 10:00. everyone will have drinks and socialize. by 11:00 or 11:30 people figure out what they will do for the rest of the night. some decide to have sex, some stay in the kitchen and drink all night. >> this attracts a lot of tech talent. >> we have many people that have start ups come to the parties. >> for some in the valley, that tech bent mentality is hard to turn off. >> love it irrational, love is crazy. we do things we would never do for love, can you be analytical about love? >> i feel completely

irrationally in love with my fiance. i also have a rational love with other people and i'm so lucky that he supports me in that quest. >> what is cinderella 2.0 look like to you. >> cinderella 2.0 has a lot of options, and she is not necessarily waiting for her prince to come. she is looking for her prince, maybe she has a princess on the side. in vote we have completely equated fidelity to love. we have equated sex to love, and those things don't necessarily have to go together. >> coming up, we go onset with the creator of hbos silicon valley.

>> one week to reimagine the way you live. what if society's rules didn't apply. what would you do? who would you. ? many find those answers at the black rock desert at burning man. it is an event, an experience, to bring people together and experience work and play.

it is why a number of tech sprep neuros are among the tens of thousands that descend on the desert once a year. >> weeks before there is nothing there but sand. then people descend. they build up this norm set of structures, a place to live, and in the course of two or three weeks, they go through and take it down and leave no trace at the end. it has an interesting parallel. you go where there is absolutely nothing. you have a vision for something, you create it and if it works out then amazing. >> and the idea that anything is built can be rebuilt? >> maybe, or that things don't have to be permanent or the same way. in some ways you want to leave space for the next generation to come along and have their own say on how the way things should be. >> tech ceos have attended, but the point is not the rich ceos that go, it is the spirit behind

the event. it started on baker beach when a artist burned a wooden man and dog. the culture of burning man permeates the valley and where ideas of the future come to life. >> there has always been a weird drug culture in the silicon valley. it was nerdist. but the nerds back then had to have something to do to show they're not nerds. it was either i race motorcycles, i go to dead concerts, i do drugs. now that is kind of burning man and that sort of thing. >> mike judge was the brain behind bevis and butthead and he wrote the hbo sitcom "silicon valley". >> what is funny about it? >> people don't know quite how to enjoy themselves.

it is awkward, it's like what do i spend the money on, what do i do, how do i enjoy it. everybody is using all of these apps and every day, it is part of our daily life and nobody thinks about who puts this stuff together. >> it all tends to come down to burning man. what on earth coyou do that represents this larger counter culture? >> it is like what you experience in san francisco by ten or 100. you get rejuvenated in a way to feel that freedom of thought, and you come back here and you're motivated to bring that freedom to more people. >> i loved this, and a lot of people are talking about it because it is about things that people are shy to discuss, but it is what is happening in the valley. i'm wondering what surprised you the most. >> just talking to all of these people and getting them to talk about things that people really

shy away from. but that is kind of the spirit of silicon valley, right? let's come up with something controversial, risky, often times it will fail, and sometimes it will succeed. it is interesting they're really taking that idea and applying it to some of the most personal things like relationships. drugs. these people say drugs are not bad. we think we should be with one person and they're saying we should be with five. >> did you get a sense this would trickle more into the main stream, or for people that live a life of innovation, trying, and risk taking? >> i think it is an interesting question. i think it is easier to talk about it in a place where you might be an engineer at a tech company, and it is an open environment, and you don't have to worry about losing your job. i will say that technology is

lifting. everyone is weird, right? i got the inspiration for this because i have an app called secret, and my contacts were posting about polyamory and drug use, and i wanted to look into. >> i wonder if there is any push back from people in the valley saying how could you categorize us like this -- >> it's interesting, i have a few people that said why didn't you ask me about this? but i think it did spark a little bit of a debate. there is a whole debate happening online about monogamy and nonmonogamy. >> where can people go to see the whole thing? >> you can almost binge watch all of these on the website, cnn

money. >> laurie segall reporting for us. we start now with a cnn special report "videos gone viral." thank you for watching. good evening, i'm kyra phillips, you have seen the videos countless times. images caught on tape. amazing rescues, death defying acts, killer weather, and outrageous criminals. what are the real stories behind those pictures? what really happened before and after that camera started rolling? find out in "videos gone viral." >> close calls, unexpected brushes with death, and when they're caught on camera, these death defying acts
